Product Description & Core Advantages

1. Product Overview

The XQ20 series spare parts cover a complete range of components, including rollers (XQ20-225, XQ20-76), dies (XQ20-71(1), XQ20-71(2)), die seats (XQ20-72(1)-XQ20-72(8), XQ20-226), backup tong components (XQ20-227, XQ20-228, XQ20-254), bearings (XQ20-233, XQ20-236), fasteners (XQ20-75, XQ20-231, XQ20-249), and sealing parts (XQ20-243, XQ20-245). Each part is precision-machined using high-strength alloy materials and advanced heat treatment technology, ensuring perfect compatibility with the original equipment and stable performance in harsh oilfield environments.

2. Function & Pain Point Solutions

Every component in the XQ20 series is designed to address specific on-site pain points:

• XQ20-225 Roller & XQ20-74 Roller shaft: Solve the problem of rapid wear and jamming during high-load operation, with a surface hardness of HRC 62-65, which can withstand a maximum load of 1800N without deformation, avoiding frequent shutdowns for replacement.

• XQ20-228 Backup tong body: Made of integral forging technology, it solves the problem of cracking due to uneven force during tong operation, with a tensile strength of 860MPa, ensuring safe operation under high torque conditions.

• XQ20-233 Ball bearing (GB/T276): Adopts sealed structure design, preventing dust and drilling fluid from entering, solving the problem of bearing damage caused by harsh working conditions, and extending the service life to 12,000 hours.

• Sealing parts such as XQ20-243 Oring (GB/T3452.1): Made of high-temperature and oil-resistant rubber, it solves the problem of oil leakage in the hydraulic system, with a service life of 8,000 hours under 120℃ working temperature.

3. Structural Features

The XQ20 series spare parts have obvious structural advantages that adapt to the harsh working environment of oilfields:

• Integral forging structure: Key components such as backup tong body and gear shaft are made of integral forging, which improves the structural strength and reduces the risk of fracture, compared with cast parts, the service life is increased by 3,500 hours.

• Precision machining: All parts are processed by CNC machine tools with an error of less than 0.02mm, ensuring perfect fit with the original equipment, avoiding installation difficulties caused by size deviation.

• Corrosion-resistant coating: The surface of components such as rollers and die seats is coated with a special anti-corrosion layer, which can resist the corrosion of drilling fluid and underground gas, adapting to the humid and corrosive environment of oilfields.

• Standardized design: All fasteners and sealing parts comply with national standards such as GB/T71 and GB/T3452.1, which is convenient for on-site replacement and reduces the difficulty of spare parts management.

4. Applicable Working Conditions

The XQ20 series spare parts are specially designed for the harsh working conditions of oilfield drilling, and are applicable to:

• Deep well drilling: Adapt to the high temperature (up to 180℃) and high pressure (up to 70MPa) environment of deep wells, ensuring stable operation of components.

• Offshore oilfields: The anti-corrosion coating can resist the corrosion of seawater, suitable for offshore drilling platforms.

• Heavy oil exploitation: The high-strength material can withstand the impact of heavy oil viscosity, avoiding component damage caused by high load.

• Desert oilfields: The sealed structure prevents sand and dust from entering, ensuring the normal operation of bearings and other precision components.

5. Maintenance & Maintenance Suggestions

To extend the service life of XQ20 series spare parts and ensure stable operation, our engineers provide the following practical maintenance suggestions (based on 18 years of on-site experience):

• Regular inspection: Check the wear of rollers, dies, and other easily worn parts every 500 hours of operation; if the wear amount exceeds 0.5mm, replace them in time to avoid secondary damage to other components.

• Lubrication maintenance: Apply special lubricating grease to bearings, roller shafts, and other rotating components every 300 hours, and clean the old lubricating grease before applying, avoiding the mixing of impurities affecting lubrication effect.

• Storage precautions: Spare parts should be stored in a dry and ventilated warehouse, away from moisture and corrosive substances; the surface of metal parts should be coated with anti-rust oil to prevent rust.

• Installation tips: When installing die seats and other components, ensure that the installation position is accurate, and do not force installation to avoid thread damage or component deformation; after installation, test run for 30 minutes to check for abnormal noise or jamming.

• Avoid pitfalls: Do not use non-standard spare parts to replace XQ20 series components, as this will not only affect the compatibility but also increase the risk of equipment failure; do not overload the components beyond the rated load, which will shorten the service life.
